Answer:

perimeter of square ,p = 100m

Length of each side,L =?

we know,

perimeter of square ,p = 4L

4L = 100

L= 100/4

L=25m

Length of each side is 25m

Using a formula estimate the body surface area of a person whose height is 150 cm and who weighs 80 kg.

ladessa [460]

Answer:

B. $1.83\text{ m}^2$

Step-by-step explanation:

We are asked to find the body surface area of a person whose height is 150 cm and who weighs 80 kg.

$\text{Body surface area}( m^2)=\sqrt{\frac{\text{Height (cm)}\times \text{Weight (kg)}}{3600}}$

Substitute the values:

$\text{Body surface area}( m^2)=\sqrt{\frac{150\text{ cm}\times 80\text{(kg)}}{3600}}$

$\text{Body surface area}( m^2)=\sqrt{\frac{12,000}{3600}}$

$\text{Body surface area}( m^2)=\sqrt{3.3333333}$

$\text{Body surface area}( m^2)=1.825741$

$\text{Body surface area}( m^2)=1.83$

Therefore, the body surface area of the person would be 1.83 square meters.

Help, I still cannot wrap my head around this

atroni [7]

Answer:

9 inches.

Step-by-step explanation:

Fun question! The length of a space diagonal for a cube is $\sqrt{3*sidelength^2}$

Thus, the first cube has a side diagonal of $\sqrt{3}$

The next cube would have a side diagonal of 3

The third cube would have a side diagonal of $3\sqrt{3}$

And the fourth cube would have a side diagonal of 9.

Since the fifth cube has a side length equal to the side diagonal of the fourth cube, it should be 9 inches.

Two vertices of a right triangle have the coordinates (−2, 5) and (9, 5) . What is the length of the side formed by these vertic

Anvisha [2.4K]

Note that those 2 points share the same y-coordinate (5). Thus, all you have to do is to find the distance between the x-coordinate -2 and the x-coordinate 9. That difference is 11, and that's the desired length.
